Eur Heart J:房颤患者代谢综合征与非血栓栓塞性心脏不良结局的关系

2018-08-09 xing.T MedSci原创

由此可见,代谢综合征在没有明显CAD的AF患者中很常见,并且导致MACE风险增加,包括MI、冠状动脉血运重建和心脏死亡。鉴于预后意义,预防和治疗MetS可减轻AF患者非血栓栓塞并发症的负担。

有证据表明与房颤(AF)相关的非血栓栓塞性主要心脏不良事件(MACE)的风险过高,特别是在没有明显冠状动脉疾病(CAD)的个体中。代谢综合征(MetS)会增加一般人群的血管风险,但对其如何影响AF患者的预后却知之甚少。近日,血管领域权威杂志Eur Heart J上发表了一篇研究文章,研究人员旨在评估MetS是否会影响没有明显CAD的AF患者的MACE风险。

这项前瞻性观察性研究纳入了843名AF患者(平均年龄为62.5±12.1岁,女性占38.6%),这些患者无明显CAD。根据国家胆固醇教育计划定义代谢综合征。5年复合MACE包括心肌梗死(MI)、冠状动脉血运重建和心源性死亡。

302例(35.8%)患者存在代谢综合征。在5年的随访中,118名(14.0%)患者出现MACE(2.80%/年)。代谢综合征赋予MACE多变量校正后风险比(aHR)为1.98[95%置信区间(CI)为1.23-3.16; P=0.004],并且对于单一结局:MI(aHR为2.00; 95%CI为1.69-5.11; P<0.001),血运重建(aHR为2.33; 95%CI为1.40-3.87; P=0.001)和心脏死亡(aHR为2.59; 95%CI为1.25-5.33; P=0.011)。对MetS进行倾向评分(PS)调整后,MetS与MACE(PS-aHR为1.87; 95%CI为1.21-3.01; P=0.012)、MI(PS-aHR为1.72; 95%CI为1.54-5.00; P=0.008)、血运重建(PS-aHR为2.18; 95%CI为1.69-3.11; P=0.015)和心源性死亡(PS-aHR为2.27; 95%CI为1.14-5.11; P=0.023)之间的关联仍然显著。

由此可见,代谢综合征在没有明显CAD的AF患者中很常见,并且导致MACE风险增加,包括MI、冠状动脉血运重建和心脏死亡。鉴于预后意义,预防和治疗MetS可减轻AF患者非血栓栓塞并发症的负担。
